Chrysanthemum plant named ‘GEDI ONE SOR’

ABSTRACT

A new and distinct Chrysanthemum plant variety characterized by a large decorative type inflorescence, consistent flowering response to short days, blooming consistently after 49 days of short day length, free branching habit, and consistent natural season flowering habit during the first two weeks of September.

LATIN NAME

Dendranthema morifolium.

VARIETY

‘GEDI ONE SOR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Dendranthema morifolium and herein after referred to by the cultivar name ‘GEDI ONE SOR’.

This new cultivar originated from hybridization of a female parent, cultivar ‘Dark Veria’ (U.S. Plant Pat. No. 10,215), and a male parent, cultivar ‘Orka’ (unpatented in the United States). The new cultivar was discovered by the inventor in September 1997.

Asexual reproduction of the new cultivar by apical tip cutting and meristem tissue culture was performed in Oxnard, Calif. and has shown that the unique features of this new cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘GEDI ONE SOR’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observe and are determined to be the unique characteristics of ‘GEDI ONE SOR.’ These observations were made on plants approximately 120 days old from rooted cuttings. These characteristics in combination distinguish ‘GEDI ONE SOR’ as a new and distinct Chrysanthemum:

1. Large decorative type inflorescence;

2. Consistent flowering response to short days, blooming consistently after 49 days of short day length;

3. Free branching habit; and

4. Consistent natural season flowering habit during the first two weeks of September.

Plants of the new cultivar are similar to plants of the parent cultivar, ‘Dark Veria,’ in most horticultural characteristics, however plants of the new cultivar differed from plants of the cultivar ‘Dark Veria’ in the following characteristics:

1. The new cultivar has a wider diameter flower;

2. The new cultivar has many more ray florets than the parent;

3. The new cultivar is taller and wider; and

4. The new cultivar naturally blooms 3 weeks earlier.

Plants of the new cultivar are also similar to plants of the parent cultivar, ‘Orka,’ in most horticultural characteristics, however plants of the new cultivar differed from plants of the cultivar ‘Orka’ in the following characteristics:

1. The new cultivar has a wider diameter flower;

2. The new cultivar has many more ray florets than the parent; and

3. The new cultivar is taller and wider.

The new cultivar can be compared to the Chrysanthemum cultivar ‘CLEAGAR GF1’ (disclosed in U.S. Plant Pat. No. 10,463). However plants of the new Chrysanthemum differed from the plants of the cultivar ‘CLEAGAR GF1’ in the following characteristics:

1. The new cultivar naturally blooms 2 weeks earlier;

2. The new cultivar has larger diameter blooms;

3. The new cultivar has more blooms per flowering branch; and

4. The new cultivar is taller and wider.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photograph shows a plant of ‘GEDI ONE SOR’ grown in a 2-gallon container. A single cutting was used in the pot, planted mid-May and grown under outdoor field conditions.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
